Abstract

Authors. 2018. Short Communication: Viability and environmental effect to conidial germination of antagonistic fungi that potential as biological control of Colletotrichum gloeosporoides caused antracnose disease on chili. Biodiversitas 19: 974-977. Some of antagonistic fungi from chili rhizosphere were potential to suppress the growth of colletotrichum gloeosporoides in vitro. This present study was aimed to observe the viability of antagonistic fungi and effect of temperature and ultraviolet light to its conidial germination. We targeted to obtain the isolate with the best viability and high resistance to temperature and ultraviolet changes. The experiment used a completely randomized design consisted of nine treatments and four replication. The treatment were nine of antagonistic fungi isolates from chili rhizosphere that consisted of two genera, Trichoderma and Paecilomyces, each comprised four isolates and unidentified isolate (X isolate). These four isolates were considered as replication for observation. The observed parameters observe included the width of colony, density of conidia, germination of conidia, effect of temperature and ultraviolet light changes to conidial germination. The results showed that antagonistic fungi from the genus Trichoderma had the best viability (the width of colony = 39.68-56.92 cm2, density of conidia 40.50-57.50 x 109 conidia/mL and germination of conidia > 80%) and highest resistance to temperature and ultraviolet changes compared with the other fungi used in this study.

Abstract. Nurbailis, Djamaan A, Rahma H, Liswarni Y. 2019. Potential of culture filtrate from Trichoderma spp. as biofungicide to Colletotrichum gloeosporioides causing anthracnose disease in chili. Biodiversitas 20: 2915-2920. Trichoderma spp. have the potential to be used for controlling the airborne pathogenic fungi such as C. gloeosporioides. The purpose of this study was to evaluate the antifungal activity of the culture filtrate of five isolates of Trichoderma spp. (T. harzianum, T. viride, T. koningii, Trichoderma PP2, Trichoderma PP3) against C. gloeosporoides causing anthracnose disease in chili. Culture filtrate of Trichoderma spp. was produced from single culture and dual culture techniques. The design was a Completely Randomized Design with six treatments and four replications. The treatments were culture filtrate from T. harzianum, T. viride, T. koningii, Trichoderma PP2, Trichoderma PP3, and negative control (without culture filtrate from Trichoderma spp.). Parameters observed were: the diameter of the colony, colony coverage, conidial germination, and conidial density. The results of this research showed all the culture filtrate from Trichoderma spp. produced by single and dual culture techniques can inhibit the growth of C. gloeosporioides. The culture filtrate from Trichoderma PP2 and T. koningii were the most potential in inhibiting the growth, conidial density, and conidial germination of C. gloeosporioides.

Abstract. Rahma H, Nurbailis, Kristina N. 2019. Characterization and potential of plant growth-promoting rhizobacteria on rice seedling growth and the effect on Xanthomonas oryzae pv. oryzae. Biodiversitas 20: 3654-3661. Xanthomonas oryzae pv. oryzae (Xoo), a major limiting factor in rice production, and the use of resistant Xoo varieties have failed to control the bacterial pathogens as well as increased yield. It is due to the diversity in pathotypes, caused by environmental factors, the nature of resistant variety used, and gene mutation. The aims of this study were to select rhizobacterial strains with the potential of suppressing Xoo growth and promoting the growth of rice seedlings. This experiment was conducted in a completely randomized design (CRD) using seven rhizobacterial isolates selected through a dual culture test, with four replications. There were four isolates that potential in inhibiting the growth of Xoo, namely KJKB5.4, LMTSA5.4, Bacillus cereus AJ34, and Alcaligenes faecalis AJ14, with inhibition diameters greater than 11.50 mm. Rhizobacterial supernatant of 4 potential isolates has a zone of inhibition ranging from 12.25 to 24.00 mm. Four potential isolates were also able to solubilize phosphate, produce indole acetic acid (IAA) growth hormone, and siderophore, as well as enhance the growth of rice seedlings. Based on the nucleic acid sequencing of LMTSA5.4, KJKB5.4, and RK12 isolates were identified as Stenotrophomonas malthopilia strain LMG 958 (99.13%) accession NR 119220.1, Stenotrophomonas pavanii strain LMG 25348 (95.84%) accession NR 118008.1 and Ochrobactrum ciceri strain ca-34 (92.91%) accession NR115819.1.

Abstract. Rahma H, Nurbailis, Busniah M, Kristina N, Larasati Y. 2021. The potential of endophytic bacteria to suppress bacterial leaf blight in rice plants. Biodiversitas 23: 775-782. Endophytic bacteria are potential as biocontrol agents against bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae in rice to support sustainable agriculture. This study aimed to select and characterize 22 endophytic bacteria isolated from healthy rice, determine their ability to promote plant growth and suppress bacterial leaf blight disease in rice and also identify potential endophytic bacterial isolates. The study was arranged in a Completely Randomized Design with 24 treatments and three repetitions. The treatments used in the current study consisted of Xanthomonas oryzae infected plants and treated with endophytic bacterial isolates; infected plants without endophytic bacteria treatment (positive control), non-infected plants (negative control). Identification of potential endophytic bacteria was performed based on 16S rRNA sequences. Three out of 22 bacterial isolates, i.e., LmB1, LmA6, and LmB2 were able to suppress bacterial leaf blight disease with severity levels of 35.82%, 23.78%, and 23.78%, respectively. Based on the rice plant growth parameters, three bacterial isolates (LmA6, LmB1, and LmB35) were able to increase the growth of rice plants with an average value of 69.56%, 56.51%, and 47.82%, respectively. Two bacterial isolates, i.e., LmB 1 and LmA6 suppress the development of bacterial leaf blight disease and increase the growth of rice plants. Based on DNA sequence comparisons of DNA fragments amplified by 16S rRNA related marker of the selected bacterial isolates and database, then LmA6, LmB2, LmB1, and LmB35 had similarities with Bacillus cereus MD152 (96.87%), Bacillus thuringiensis ATCC 10792 (98.20%), Ochrobactrum intermedium strain OI1 (97.52%), and Stenotrophomonas maltophilia strain A1w2 (97.92%), respectively. Our study revealed that the indigenous endophytic bacteria from rice plants could be potential biological agents for controlling bacterial leaf blight disease and increasing plant growth.

Abstract. Nurbailis, Yanti Y, Resti Z, Djamaan A, Rahayu SD. 2023. Consortia of endophytic bacteria for controlling Colletotrichum gloeosporiodes causing anthracnose disease in chili plant. Biodiversitas 24: 3503-3511. Anthracnose disease caused by Colletotrichum gloeosporioides is the main disease in chili plants, which reduces yields by up to 90%. Using a consortium of endophytic bacteria is an alternative way to control the disease at a low cost and is environmentally friendly. The aim of the study was to obtain the best consortium of endophytic bacteria to control anthracnose caused by C. gloeosporioides and improve the growth and yield of chili plants. This research was arranged in an experimental method consisting of two stages, namely (i) compatibility test between endophytic bacterial consisting of 28 species, and (ii) test of the endophytic bacterial consortium ability to control anthracnose in chili using a Completely Randomized Design (CRD) with 14 treatments and provided with 3 replications. All treatments of endophytic bacterial consortium showed the potential to suppress anthracnose disease caused by C. gloeosporioides and improve the growth and yield of chili plants. The best bacterial consortium treatment in suppressing the development of anthracnose disease by C. gloeosporioides and increasing the growth and yield of chili plants was the consortium B. cereus SNE 2.2 + B. cereus TLE 1.1 with dis-ease severity of 0.00%, plant height of 58.33 cm and fruit weight of 208.97 g.
